Filed: 1942-03-02
Abstract: 564,991. Thermostats. DEHN, F. B. (Chicago Flexible Shaft Co.). March 2, 1942, No. 2732. [Class 64 (ii)] [Also in Group XXXVII] A bimetallic strip 32, Figs. 1 and 3, is secured by a screw 16 to a surface 15 to which it is to be temperature-responsive, and the opposite end is confined against lateral and angular movement by abutments 18, 19. The strip is stressed endwise by a screw 22 for snap action, and a screw 23 limits the downward movement. The high-expansion side is uppermost, and the strip is curved so as to be concave upwardly when cold. A leaf spring 26 is pivoted at 25 and is adjusted by a screw 31 so that an insulated button 27 exerts a variable pressure on the strip and thereby adjusts the temperature at which the strip moves the contact 28 into or out of engagement with contact 29. The part 32 of the strip tapers inward towards the centre and the part 33 has a serpentine configuration, whereby the constraint imposed on angular movement of the end of the part 32 is limited. In amodification, Figs. 5-8 (not shown), the strip is secured by screws at both ends, serpentine portions are provided at both ends, and the strip tapers from the centre towards both ends. This modification is responsive to the temperature of a surrounding gas. In another modification. Fig. 11, the thermostat is not snap-acting. The free end of the strip, which is of form shown in Fig. 1, is rigidly secured to a spring strip 26 by a pin 56, whereby angular movement of this end of the strip is prevented. By a suitable configuration of the more flexible portions of the strip, a compensation for time lag can be obtained.

Title: Improvements in or relating to the manufacture and use of perfumes
IPC: C11D9/44
Filed: 1942-03-17
Abstract: 556,117. Toilet soap; perfumery. LUSH, E. J., and LUNT & CO., Ltd., P. March 17, 1942, No. 3491. [Class 91 ] [Also in Group VI] Soap, face powder, and other toilet preparations are perfumed by the addition of a perfume of the phenolic type added as its alkali metal salt. The alkali salt may be one formed directly from the perfume, such as thymol, or one formed from an isomer which has been obtained by treatment of the original perfume with the alkali, such as isolugenol obtained by heating lugenol with potash, the salt resulting by using excess of the alkali. Of the latter type, the potassium salt of isosafrol is also specified; this salt mixed with potassium isoeugenate is also described. The salts may be used blended with perfumes of the non-phenolic type. The free perfume is liberated from its salt by the carbon dioxide of the air and may additionally be modified by partial oxidation; thus potassium isoeugenate gives the odour of isoeugenol with a suggestion of vanillin. The toilet preparation, such as soap, may be deliberately matured in an atmosphere of carbon dioxide. The fatty acids of the soap base or other fatty acids may be added as free acids to neutralize any excess alkali. Part of the perfume may be freed by the further addition of fatty acids or another phenolic perfume such as guaiacol.
